We still run E2E tests before deployment, but running them on pull requests also eliminates the question: "We want to deploy, but have a bug. Which PR caused it? and how do we fix it?" This approach essentially saves you from having to perform a git bisect and engineers getting blocked because there is a bug unrelated to their task.

Just run them on every commit in develop branch after the PR is merged. Then you can always roll back or revert the merge and leave it to the PR author to fix it.
